The U.S. Copyright Act (section 106), which I will take as typical, says:

# § 106. Exclusive rights in copyrighted works
# Subject to sections 107 through 120, the owner of copyright under this title
# has the exclusive rights to do and to authorize any of the following: [...]
# (2) to prepare derivative works based upon the copyrighted work [...].

"Prepare", not merely "distribute".
